They mentioned the area in their NE Pacific Tropical discussion.

TROPICAL WEATHER DISCUSSION
NWS NATIONAL HURRICANE CENTER MIAMI FL
2205 UTC SUN MAY 08 2016

...DISCUSSION...

HIGH PRESSURE RIDGE PREVAILS OVER THE NORTHERN WATERS. THE
PRESSURE GRADIENT BETWEEN THE AREA OF HIGH PRESSURE AND LOWER
PRESSURE IN THE VICINITY OF THE ITCZ IS SUPPORTING MODERATE TO
FRESH TRADES OVER THE WESTERN WATERS NORTH OF THE ITCZ. THE
FRESH WINDS HAVE HELPED GENERATE A TRADEWIND SWELL WHICH IS
COMBINING WITH NW SWELL TO HELP FOR COMBINED SEAS REACHING 9 FT
FROM 08N TO 20N W OF 125W AS DEPICTED FROM THE MOST RECENT
ALTIMETER PASSES. THE RIDGE WILL REMAIN OVER THE AREA BUT WILL
WEAKEN SLIGHTLY. THIS WILL DIMINISH WINDS AND SEAS WILL SUBSIDE
BELOW 8 FT OVER THIS AREA BY TUESDAY.

A KELVIN WAVE PROPAGATING ACROSS THE AREA HAS HELPED INDUCE
SURFACE WESTERLIES AS FAR WEST AS 123W AS DESCRIBED IN THE
ITCZ/MONSOON TROUGH SECTION ABOVE. THE KELVIN WAVE HAS HELPED TO
DEVELOP A SURFACE LOW NEAR 10N113W WITHIN THIS MONSOONAL TROUGH.
WHILE WINDS REMAIN 20 KT OR LESS ASSOCIATED TO THIS LOW...SEAS
OVER THE SE QUADRANT ARE REACHING NEAR 9 FT WHERE WINDS ARE
REACHING NEAR 20 KT. THE LOW PRESSURE AREA WILL REMAIN FAIRLY
STATIONARY OVER THE NEXT COUPLE OF DAYS.

Is worthy of a mention.


Looking healthy.

A WELL-DEFINED SURFACE 1009 MB LOW IS PRESENT AT 11N109W
EMBEDDED ALONG THE MONSOON TROUGH. SCATTERED MODERATE CONVECTION
EXISTS WITHIN 180 NM OF CENTER. PEAK WINDS IN ITS CIRCULATION
ARE LIKELY AROUND 20 KT...BUT NO IN-SITU OR SCATTEROMETER
OBSERVATIONS HAVE BEEN AVAILABLE DURING THE LAST SEVERAL HOURS.
OVERNIGHT THE CONVECTION EXHIBITED SOME BANDING FEATURES...
THOUGH THESE WERE TRANSIENT AND NOT ENOUGH TO BEGIN DVORAK
CLASSIFICATIONS. THE LOW IS ANTICIPATED BY ALL GLOBAL MODELS TO
MAINTAIN ITS CURRENT INTENSITY FOR THE NEXT FEW DAYS AND NOT
DEVELOP INTO A TROPICAL CYCLONE...AS IT MOVES WEST-
SOUTHWESTWARD. IT IS LIKELY TO BECOME ABSORBED WITHIN THE ITCZ
BY MONDAY OR TUESDAY. THE COMBINATION OF LONG-PERIOD SW SWELL
INTERACTING WITH THE NE WINDS IN THE NW SEMI-CIRCLE OF THE LOW
WILL PRODUCT SEAS TO 8 FT OVER THE NEXT FEW DAYS.

Not when it is attached to the ITCZ/Monsoon trough and not much if any model support for development, IMO.

I've seen worse looking invests and some that were still attached.

Also what's up with ITCZ? It's really high for this time of the season.

Colder SST's in the CATL and Nino 1+2 leading to higher pressures, forcing the ITCZ northward.

Like 2013, we should see a lot of storms off the west coast of Baja this year for this reason. But the SST's there are a bit warmer than they were in 2013, so the odds of a low ACE season are diminished unless the current SST profile causes shear.

Lows spin-up whilst still attached to the MT happens all the time.

Thank you for the explanation.

Nice blowup of convection near or over the center now. Shear looks like it will be a problem still but I wonder if the models will go back to their older depictions.

At least they have a hybrid Invest without a number as a floater.

Very deep convection associated with this low. Looks like it needs a tag again. Euro bottoms it out @ 1005mb.

Tomorrow is the 15th so maybe we'll get a marker.

looks like it could be an invest soon with maybe some modest strengthening but don't see a named storm from this unless it seperates from the ITCZ

No development on 0z Euro, it is heading into a higher shear zone.

First TWO of 2016 that includes the area of disturbed weather but no development is expected.


TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
500 AM PDT SUN MAY 15 2016

For the eastern North Pacific...east of 140 degrees west longitude:

An area of disorganized showers and thunderstorms located about
1100 miles southwest of the southern tip of the Baja California
Peninsula is associated with a weak area of low pressure. Any
development of this system is expected to be slow to occur during
the next couple of days while it moves westward at around 15 mph.
After that time, upper-level winds are expected to become less
conducive for development.
* Formation chance through 48 hours...low...10 percent
* Formation chance through 5 days...low...10 percent

Today marks the first day of the eastern North Pacific hurricane
season, which will run until November 30. Long-term averages for
the number of named storms, hurricanes, and major hurricanes are
15, 8, and 4, respectively.

Code: Select all

The list of names for 2016 is as follows:

This product, the Tropical Weather Outlook, briefly describes
significant areas of disturbed weather and their potential for
tropical cyclone formation during the next five days. The issuance
times of this product are 5 AM, 11 AM, 5 PM, and 11 PM PDT. After
the change to standard time in November, the issuance times are 4
AM, 10 AM, 4 PM, and 10 PM PST.

A Special Tropical Weather Outlook will be issued to provide
updates, as necessary, in between the regularly scheduled issuances
of the Tropical Weather Outlook. Special Tropical Weather Outlooks
will be issued under the same WMO and AWIPS headers as the regular
Tropical Weather Outlooks.

A standard package of products, consisting of the tropical cyclone
public advisory, the forecast/advisory, the cyclone discussion, and
a wind speed probability product, is issued every six hours for all
ongoing tropical cyclones. In addition, a special advisory package
may be issued at any time to advise of significant unexpected
changes or to modify watches or warnings.

The Tropical Cyclone Update is a brief statement to inform of
significant changes in a tropical cyclone or to post or cancel
watches or warnings. It is used in lieu of or to precede the
issuance of a special advisory package. Tropical Cyclone Updates,
which can be issued at any time, can be found under WMO header
WTPZ61-65 KNHC, and under AWIPS header MIATCUEP1-5.

All National Hurricane Center text and graphical products are
available on the web at http://www.hurricanes.gov. You can also
interact with NHC on Facebook at https://www.facebook.com/NWSNHC.
Notifications are available via Twitter when select National
Hurricane Center products are issued. Information about our east
Pacific Twitter feed is available at

A few runs ago the ECMWF had some development, but not anymore. Not sure if there's anything to see here but it's a sign the El nino effects from last season are still evident.

The way the tropical Pacific is set for a very rapid transition into La Nina, I'm using 2010 as the analog for such a hard and fast transition, which tied for the fewest named storms and set the record for the fewest hurricanes in the short recorded history of the EPAC. It will be very, very different from the past 4 years.
